I sometimes have a strange noise when turning left. After a while I don't hear it. But when the my cat has been still for a while and I run it. Then it will sound like:

tuck tuck tuck tuck... the sounds is about a little less than a second apart. Only when steering left. It sounds like it is coming from the left backside of the cat.

I hear it when running about 10 to 30 mph. After running the atv fore some minutes i don't hear it.

Any hints? It is an AC 400 2007. Auto. I have serviced it by the book. It is strange, because I think the sound has the same interval about a sec. even if I am running in 10 or higher mph. At least what i think.

Seriously tho. Sounds kinda like a cv joint. Might want to check for a torn boot. Or possibly may have a stick wedged somewhere but then seems like frequency would change. Had that happen on my truck once bout drove me batty.

 

could be a bearing. When turning left, the bike will put pressure on the inside of the left tires.

 

I had the same thing on my 03 except on the right side and it was the cv joint... i needed to replace te axel.

 

I have seen a bad wheel bearing that causes the CV joint to click as you have described.

I would start by removing the left rear wheel/hub and inspect the bearings. (You may want to do this all the way around) If the bearings look good then you may have to go farther on the left rear side and inspect the cv joint as it could be the outter or the inner cv joint going bad.

Mountainclimber did you have to replace the axle because it was cheaper than trying to replace the cv-joint? I think that is waht I found last time I looked at that for someone.

I remove wheels, check and repack my wheel bearing once a year. I usually have to repalce the seals ($4 each) and the cotter pin ($0.59) but this is far better than getting water in there not knowing about it and having to replace the $50+ wheel bearing.
